In the future, we     1    (live) in smart homes that will keep us secure, save us energy, and provide a more comfortable environment. Smart homes will control just    2    everything in our home. They will use integrated     3    (sensor) to go into an energy-efficient mode all by itself when we leave home. In     4    (add), smart homes will be monitoring our health every day. If they find there is something    5    (normal) or you have a critical illness, they will give you a     6    (warn) early on and    7    (potential) save our life.Smart homes will also be able to prevent serious damage from accidents. If they find something wrong they will detect    8    and provide us with the relevant information for us    9    (fix) the problem. In a word, this smart technology is not a fantasy, and it will take some years    10    most new homes begin to use this new technology.

Get ready and you will enjoy a space travel. The sky outside your spacecraft is     1    (most)black. The planet you’re looking for is 4.65 billion miles away. Almost no light     2     (reach) it. Suddenly you see a glow (暗光) in the     3     (distant). As you approach, it becomes bigger and stranger. The light     4       (shine) ahead of you is bright pink. Getting closer, you realize     5     is giving off this glow. It’s a magenta (紫红色的) planet!

    6     (name) GJ 504b, the planet is made of pink gas. It’s similar to Jupiter, a giant gas planet in our own solar system. But GJ 504b is four times more massive. At 460°F, it’s the temperature of a hot oven, and it’s the planet’s intense heat that causes it     7     (glow).

You stop your spacecraft to take     8     close look. The sky turns pink as you enter GJ 504b’s atmosphere. Since GJ 504b is made of gas, it has no solid surface. So you can fly right inside the planet, in which the gas envelops you like a thick fog. As you go     9     (deep), the gas begins to get darker. If you keep going down, your spacecraft could melt from the heat. You get away from this pink world and back     10    the darkness of outer space.

Have you ever forgotten     1     (lock) the door of your house? Or, have you ever forgotten to switch off the TV or computer? These kinds of things happen to us all the time, waste resources, and can sometimes lead     2     problems.

However, in the not-too-distant future, we will     3     (live) in smart homes that will lock the door for us when we are away and remember to switch off the TV when we forget.

You will no longer have to think about turning     4     (switch) on and off yourself. Your home will also learn your     5    (day) routine and preferences, so everything will be ready for you when you get home each evening. Your lights will come on     6     instant you enter the door along with your favourite music or TV programmes, and you will find your dinner already     7     (prepare) for you.

In addition, your smart home will be monitoring your health for you every day. If you start to have sleep or weight problems, it will send a warning to your phone. It will also give you suggestions on a     8     (health) diet and     9     to sleep better. Smart toilets will be keeping constant track of your health as well. They can warn you early on if there is something     10     (normal) or if you have a critical illness, such as cancer, and potentially save your life.

Smart homes will be able to prevent serious damage from accidents. Nevertheless, it will take some years before most new homes begin to use this new technology.

Scientists and engineers     1     (prepare) for possible travel into interstellar space, the area in between stars, in the distant future. Experts believe it will likely take many years before the technology and equipment are developed     2     (send) humans to this unexplored area of space. But if it does happen, massive spaceships     3     carry humans on long trips to distant stars.

Two American researchers, Andrew McKenzie from the University of Kansas and Jeffrey Punske of Southern Illinois University, have explored one possible problem with such travel. They considered the possibility    4     changes in human language could develop over time, thus    5    (cause) major communication problems with people on Earth.

Languages naturally changes as communities grow more isolated from each other, the researchers noted in the paper. The long isolation of a community could lead to enough differences in language to make    6    impossible for community members back home to understand.

The researchers noted that in addition to new words being used, the language of people traveling on spaceships and living in colonies    7     (experience) many other changes. For example, the sounds of different letters would likely change over time, affecting not only individual words, but the whole grammatical system.

The researchers say one possible solution to    8    (limit) communication problems would be to include language experts on spaceship crews. Another suggestion is to use sign language as a form of communication. McKenzie added that space travelers might question whether it is even worth trying to learn how to communicate with people on Earth. But he believes there will always be a need, even    9    it is very limited. “You have to learn a little Earth English to send messages back, or to read the instruction manuals and information    10    came with the ship,” he said.

The 2020 Nobel Prize in Chemistry     1    (award)to Emmanuelle Charpentier and Jennifer A. Doudna recently. The two female scientists won the prize     2     the development of a method of genome (基因组) editing.

Gene editing has a wide     3    (apply) across the world. It can     4     (direct) change the DNA of a lifeform and has the potential of leading to     5    (benefit) results.

One of the most convenient methods of gene editing is called CRISPR/Cas9,     6     was discovered by the two Nobel winners. The method enables scientists to cut a sequence of DNA into two pieces,     7    (allow) nature to “repair” it. During the repair process, errors will be introduced to create a different sequence of DNA, thus resulting in an     8    (edit) gene.

In simple words, CRISPR/Cas9 is the “scissors” of genes. The greatness of CRISPR/Cas9 lies in extreme accuracy. It also enables humans to breed (孕有) more plant varieties and develop better treatment of cancer.

In the future, the discovery     9    (expect) to have a revolutionary impact on the life science and make the dream of curing some diseases come true.

There will be no traditional Nobel Awarding Ceremony in Stockholm this year due to the COVID-19,     10     an online version will be held instead.

I am taking up the prize to travel to 3008. I can’t believe it so I have to remind myself     1     (constant). I have no previous experience, so at first I was uncertain. Luckily, my friend and guide Wang Ping was very     2     (understand) and gave me much help.     3     (transport) by Wang Ping’s parents’ company, I arrived in the future in     4     time capsule. At first my new surroundings were difficult to tolerate. So I felt     5     (comfortable) for lack of fresh air. Wang Ping gave me a mask and hurried me through a small room for a rest. Soon I was back     6     my feet again. Then I followed Wang Ping     7     (collect) a hovering carriage driven by computer.

Soon I could fly as swiftly as Wang Ping.     8     I lost sight of him with too many carriages flying by in all directions. He was swept up into the center of them.     9     (arrive) at a strange-looking house, he showed me into a large room. It’s fascinating. I had a meal and had a bath there. Exhausted, I     10     (slide) into bed and fell asleep.
